Explanation
If you think something is amazing, astounding, or marvelous, you can also call it phenomenal. Your dog's phenomenal performance at the agilty competition earned her a blue ribbon — and a handful of biscuits. Phenomenal things aren't just cool — they're truly remarkable and possibly even unique. Your sister's campaign to raise money for cancer research, which amassed a million dollars in two weeks? That's phenomenal. And Serena Williams, having won an unprecedented 23 Grand Slam titles, is without question a phenomenal tennis player. This extraordinary word comes from the relatively ordinary Greek phainomenon, "appearance," and its Proto-Indo-European root bha-, "to shine."
